OpcUaApplicationHost left ServerConfiguration.MaxRegistrationInterval at the SDK default (30000) with a null RegistrationEndpoint, so SDK 2.0.1's StandardServer armed its registration timer against opc.tcp://localhost:4840, which on an OtOpcUa node is the server itself (no LDS). It answered BadServiceUnsupported and the SDK retried forever, visible since #874. Registration is now opt-in: ApplyDiscoveryRegistration sets MaxRegistrationInterval = 0 (the value that keeps StandardServer from arming the timer) unless OpcUa:DiscoveryServerUrl is set, in which case the server registers against that URL every OpcUa:DiscoveryRegistrationIntervalMs (default 30000) over SignAndEncrypt/Basic256Sha256, like the SDK's own default endpoint. The validator requires an absolute opc.tcp:// URL and a positive interval when the URL is set. Documented in Configuration.md and OpcUaServer.md. Co-Authored-By: Claude <noreply@anthropic.com>
